FIELD

An artificial ocular lens (AOL), in particular an accommodating artificial ocular lens (AAOL) device. A preferred embodiment of the accommodating artificial ocular lens (AAOL) device according to the present invention includes a posterior chamber accommodating artificial ocular lens (pc-AAOL) device for use in the posterior chamber of the eye outside the capsular bag or inside the capsular bag (i.e. after cataract or clear natural lens removal). Preferably, the accommodating artificial ocular lens (AAOL) according to the present invention is a deformable accommodating artificial ocular lens (AAOL) for implantation through a small incision in the eye.

Also, an intraocular lens (IOL) device, for example, an accommodating intraocular lens (AIOL) device providing accommodation of vision of the eye.

BACKGROUND OF THE INVENTION

Currently, there exists a high level of cataract lens surgeries performed in the United States and in other countries and territories throughout the world. These cataract lens surgeries involve the removal of the natural lens, typically by phacoemulsification, followed by the implantation of an aphakic intraocular lens (AIOL). Further, more recently phakic intraocular lens (PIOL), for example, the implantable contact lens (ICL) are implanted with the natural lens still intact.

Most lens surgeries are performed using an intraocular lens providing little if any accommodation of the eye. Specifically, the intraocular lens is implanted into the eye, and once healing of the eye has occurred, there is very little movement of the intraocular lens in a manner to focus the eye by accommodation like the natural crystalline lens of the eye.

There has been much interest in creating and designing intraocular lens configured to provide accommodation the same or similar to the natural crystalline lens of the eye, or provide accommodation in an alternative manner. It is believed that the next generation of intraocular lenses will be accommodating intraocular lenses that provide a significant amount of accommodation of at least one (1) diopter or more. So far, most accommodating intraocular lenses being clinically studied provide one (1) diopter or less of accommodation of the eye. Thus, there now exists a need for an accommodating intraocular lens that can provide a substantial amount of accommodation of the eye, desirably, providing one (1) or more diopters of accommodation of the eye.

The subject matter is directed to an intraocular lens (IOL), for example, an accommodating intraocular lens (AIOL) configured to provide for substantial accommodation of the eye once implanted.

There has been much interest in creating and designing intraocular lenses (IOLs) configured to provide accommodation the same or similar to the natural crystalline lens of the eye. It is believed that the next generation of intraocular lenses (IOLs) will be accommodating intraocular lenses (AIOLs) that will provide a significant amount of accommodation of at least one (1) diopter or more. So far, most accommodating intraocular lenses (AIOLs) being clinically studied provide one (1) diopter or less of accommodation of the eye. Thus, there now exists a need for an accommodating intraocular lens that can provide a substantial amount of accommodation of the eye, desirably, providing one (1) or more diopters of accommodation of the eye. Further, there now exists a need for an accommodating artificial ocular lens (AAOL) configured to be inserted into the posterior chamber of the eye outside the capsular bag with the natural lens in place or removed, or inside the capsular bag.

The present invention is directed to an accommodating artificial ocular lens (AAOL) device such as an accommodating intraocular lens (AIOL) device configured in a manner that may provide for substantial accommodation of the eye.

The subject matter of this application is directed to an Artificial ocular lens (AOL) device, in particular an accommodating artificial ocular lens (AAOL) device. For example, the present invention is directed to an accommodating artificial ocular lens (AAOL) device for implanting into the posterior chamber of the eye outside the capsular bag (with or without the natural lens removed) and an accommodating artificial ocular lens (AAOL) device for implanting into the capsular bag of the eye, or otherwise an accommodating intraocular lens (AIOL) device.

The accommodating artificial ocular lens (AAOL) device comprises or consists of a moving lens optic portion. Specifically, the lens optic portion is supported for movement by a lens haptic portion. The lens optic portion is moved when the lens haptic portion is bowed or vaulted through used of flexible connecting arms connecting the lens optic portion to the lens haptic portion. The flexible connection arms move the lens optic portion forward and backward along the central focal axis of the eye during the accommodation process. In preferred embodiment, the lens optic portion is provide with at least one toric, multi-focal and/or wavefront features (e.g. modified or customized lens surfaces and/or lens interiors). Thus, the subject matter provides for a moving toric, multi-focal and/or wavefront lens optics (e.g. translational and/or tilting and/or rotating movement of lens optic) providing a combined or even synergistic effect for increasing the extent, amount or degree of accommodation (e.g. less distance of movement required of lens optic to provide same degree of accommodation).

The accommodating artificial ocular lens (AAOL) device comprises or consists of a lens optic portion connected to a lens haptic portion, preferably a lens plate haptic portion. The lens optic portion can be a hard intraocular lens optic made of a hard or non-deformable material (e.g. polymethylmethacrylate (PMMA) or hard type optically clear polyimide), or can be a soft or flexible or deformable intraocular lens optic made of a soft, flexible, resilient, foldable, compressible and/or otherwise a deformable material I, in particular a substantially deformable material (e.g. silicon, collagen-containing polymer, acrylic, polyimide, soft type polyimide, polyether, polyamide, polyester, polysulfone, polyethersulfone and other biological compatible materials of suitable refractive index).

A particularly preferred material for making the artificial ocular lens (AOL) device and accommodating artificial ocular lens (AAOL) device is an optically clear polyimide material having a refractive index of 1.5, more preferably 1.6, and most preferably 1.7 or higher. The polyimide material preferably has an optical transmittance of ninety percent (90%) or higher, a specific gravity of 1.2 (1.4 maximum), a durometer hardness of 40 to 60 shore A, a tensile strength of approximately 750 psi, an elongation of fifty percent (50%), a tear strength of 100 PPI (50 PPI minimum), and a water absorbtion of one percent (1%) maximum with hydrolytic stability. Further, the polyimide material should be foldable (i.e. folded onto itself for 5 minutes and then released), and sterilizable (i.e. not affected by standard 18 hr 8/12 ethylene oxide cycles, or 1 hr standard 250 F autoclave cycles, and medical grade (i.e. not toxic, carcinogenic, or mutagenic).

The lens plate haptic portion is preferably made of a soft, flexible, resilient, foldable, compressible and/or deformable material, and configured to allow the lens plate haptic portion to bow when an inwardly directed force is applied to the edges or edge portions of the lens plate hapic portion and/or pressure is exerted on the back surface of the capsular bag to move the lens optic portion forward to provide accommodation of the eye. The accommodating artificial ocular lens (AAOL) device according to the present invention can be made as a single piece lens (e.g. by molding or machining), or can be made as a multiple-piece lens assembled together (e.g. hard or soft lens optic portion connected to a separate soft or deformable lens plate haptic portion made of a soft, flexible, resilient, foldable, compressible and/or deformable material).

For example, the lens optic portion of the accommodating artificial ocular lens (AAOL) device remains substantially fixed in size and shape (i.e. fixed conformation) after implantation into the eye, and also remains fixed during accommodation. Specifically, the lens optic portion remains in a fixed conformation, and is not itself bent or bowed once implanted in the eye while the lens haptic portion bows to move the lens optic portion. In this fixed lens optic portion conformation or arrangement, the lens optic portion provides stable or fixed optical characteristics or performance while moving or accommodating within the eye. However, it is to be noted that the lens optic portion, in particular for a soft or deformable type accommodating artificial ocular lens (AAOL) according to the present invention, can be substantially deformed, rolled, compressed or folded for insertion through a small incision (i.e. 3.5 mm or less) and then implanted into the eye.

In another example, the lens optic portion can be configured to tilt (e.g. relative to capsular bag and/or lens plate haptic portion) to provide and/or improve accommodation or during accommodation within the eye. Specific, the lens optic portion is configured so that the optical power of the lens optic portion changes with increased angle of tilt from a reference plane set perpendicular relative to the optical axis of the eye. The lens optic portion can be configured so that the power of the lens optic portion is proportional to the angle of tilt, or alternatively, the lens optic portion can be configured so that the power of the lens optic portion changes exponentially to the angel of tilt.

The accommodating artificial ocular lens (AAOL) device comprises or consists of a lens optic portion and a lens haptic portion, preferably a lens plate haptic portion. The lens optic portion is essentially a separate component from the lens haptic portion except for at least one flexible or resilient arm connecting the lens optic portion to the lens haptic portion. Preferably, at least one opening is provided between an outer edge of the lens optic portion and an inner edge of the lens plate haptic portion. More specifically, the lens optic portion is separated from the lens plate haptic portion by a predetermined fixed or varying distance or spacing. In this arrangement, the outer edge of the lens optic portion is able to move substantially freely and independently relative to the inner edge of the lens plate haptic portion except at the point or points of connection with the flexible or resilient arm(s). Preferably the sizing of the haptic is customized to the particular patient's eye.

The accommodating intraocular lens (AIOL) comprises or consists of at least one arm, preferably a flexible or resilient arm connecting the lens optic portion to the lens plate haptic portion. The flexible or resilient arm is configured to move the lens optic portion along the central focus axis of the eye when the lens plate haptic portion is bowed, for example, when the eye exerts an inwardly directed radial force at one or more positions around the outer edge of the lens plate haptic portion. More specifically, the lens optic portion is moved back-and-forth along the central focal axis of the eye for purposes of accommodation for focusing the eye when the lens plate haptic portion is bowed and unbowed. At least one flexible arm allows the outer edge of the lens optic portion to move relative to the inner edge of the lens plate haptic portion, which becomes distorted as the lens plate haptic portion is bowed. In this manner, the at least one flexible or resilient arm undergoes tensile stress, shear stress, pressure, and some tortional stress when the lens plate haptic portion is bowed without breaking or without permanently deforming. Specifically, the stresses are at a level within the at least one flexible or resilient arm when the lens plate haptic portion is bowed so as to not cause plastic deformation of the at least one flexible or resilient arm. Thus, when the force on the outer edge of the lens plate haptic portion is relieved and/or pressure is relieved behind the lens, the stresses within the at least one arm are relieved and causes the lens optic portion to move back to a resting position relative to the eye.

In some examples of the accommodating artificial ocular lens (AAOL) device, the lens optic portion is initially located in the same plane as the lens plate haptic portion. When force is applied to the outer edge of the lens plate haptic portion, the lens plate haptic portion begins to bow and moves the lens optic portion out of the initial reference plane along the central focal axis of the eye. As the lens plate haptic portion bows, it changes shape substantially from a two-dimensional (2-D) configuration to a cupped or bowed three-dimensional (3-D) configuration, and is substantially no longer planar.

The outer periphery or edge portion of the lens plate haptic portion is preferably configured and/or treated to facilitate or enhance anchoring thereof within the eye. Specifically, the lens plate haptic portion can be provided with one or more through holes to allow tissue on either side of the lens plate haptic portion to adhere together in and through the hole. Alternatively, or in addition, the outer edge of the lens plate haptic portion can be provided with scallops, serrations, notches, protrusions, pins, fingers to facilitate tissue adherence thereto.

Further, preferably the outer edges of the lens plate haptic portion is provided with one or more shape edge portions. For example, the lens plate haptic portion is cut by stamping through the thickness of the lens plate haptic portion to form an upper sharp edge and lower sharp edge. The radius of curvature (i.e. bevel or blend) of these sharp edges is preferably twenty-five (25) microns or less, more preferably ten (10) microns or less, and most preferably five (5) microns or less. The sharper the upper and lower outer perimeter edges of the lens plate haptic, the better the lens plate haptic portion prevents the growth of cells onto the lens plate haptic and lens optic portion when the accommodating artificial ocular lens (AAOL) device is implanted in particular into the capsular bag.

The stamp for making the sharp edges of the lens plate haptic portion is preferably diamond polished at the cutting edges to desirably achieve a radius of curvature of twenty-five microns or less.

In some examples of the accommodating artificial ocular lens (AAOL) device, the lens haptic portion is circular-shaped or substantially rectangular shaped. Further, preferably the lens optic portion is centered relative to the shape of the outer periphery of the lens plate haptic portion.

In another example, the accommodating artificial ocular lens (AAOL) device comprises or consists of a lens optic portion located off center in one or both the length and width dimensions of the lens plate haptic (i.e. relative to the outer perimeter shape of the lens plate haptic portion). In this manner the accommodating artificial ocular lens (AAOL) device can be customized to take into account the morphology of the interior of the eye of a particular patient in custom designing and prescribing the particular accommodating artificial ocular lens (AAOL) device for said patient.

In a further example, the accommodating artificial ocular lens (AAOL) device comprises or consists of a pair of flexible or resilient arms connecting the lens optic portion to the lens plate haptic portion, the lengths of the arm portions being the same or different to center or off-center the lens optic portion relative to the central optical axis of the eye. Further, the location of the pair of arm portions can be located along a center axis of the lens optic portion, or can be located off axis again to center or off-center the lens optic portion relative to the central optical axis of the eye.

In an even further example, the accommodating artificial ocular lens (AAOL) device comprises or consists of a lens optic portion connected to a lens plate haptic portion so that the lens optic portion is tilted relative to said lens plate haptic portion or central focal axis to provide accommodation by tilting and untilting of the lens optic portion changing its effective lens power. Specifically, the artificial ocular lens (AAOL) device is configured or designed to purposely tilt the lens optic to continuously increase the lens power linearly or exponentially proportional relative to the increase in tilting angle. For example, in some embodiments, the angle of tilt remains linear or fixed during bowing of the lens haptic portion, and in other embodiments, the angle of tilt progresses or regresses exponentially based on the extent of bowing of the lens haptic portion. In a further embodiment, the lens optic portion is not tilted relative to the central focal axis of the eye initially (e.g. lens optic portion is located in same plane as lens plate haptic portion initially), and then the lens optic portion progressively tilts relative to the central focal axis of the eye as the lens haptic portion is bowed.

As another example, the accommodating artificial ocular lens (AAOL) device comprises or consists of a multi-focal lens optic portion. The multi-focal lens optic portion provides two or more lens power once implanted in the eye (e.g. bifocal, trifocal, four or more lens powers or different power regions or zones).

The accommodating artificial ocular lens (AAOL) device can be configured to replace the natural crystalline lens of the eye (e.g. an accommodating intraocular lens (AIOL) device for implantation into the capsular bag or an accommodating artificial ocular lens (AAOL) device for implantation into the anterior or posterior chamber of the eye outside the capsular bag). Alternatively, the accommodating artificial ocular lens (AAOL) device according to the present invention can be an accommodating refractive correction lens (ARCL) device configured to be implanted into the eye with the natural crystalline lens intact or combined with an implanted intraocular lens (IOL) device as an additional or supplemental lens (i.e. multiple lens system, two lens system, three lens system, four or more lens system).

For example, an accommodating refractive correction lens (ARCL) device can be a soft or deformable phakic accommodating refractive correction lens (pARCL) device (i.e. accommodating refractive correction lens device added to eye having a substantially healthy or fully functioning natural crystalline lens), or an aphakic supplemental accommodating refractive correction lens (ap-sARCL) device (i.e. accommodating refractive correction lens device added to an eye having an implanted IOL) configured to be implanted through a very small incision in the eye (i.e. 2 mm or less, or preferably 1 mm).

As another example, the accommodating refractive correction lens (ARCL) is a soft or deformable anterior chamber phakic accommodating refractive correction lens (ac-pARCL) device or aphakic supplemental accommodating refractive correction lens (ap-sARCL) device configured to be implanted through a very small incision in the eye.

As an even further example, the accommodating artificial ocular lens (AAOL) device is a soft or deformable custom accommodating artificial ocular lens (c-AAOL) device configured to be implanted through a very small incision in the eye.

Specifically, a custom accommodating artificial ocular lens (c-AAOL) device according to the present invention preferably corrects at least two (2), and more preferably at least three (3) visual problems or defects (e.g. accommodating problems, optical problems, power problems, astigmatic problems, refractive problems, tissue problems, impairments, abnormalities, disease or other factors or conditions impairing or negatively affecting a patient's vision). In a preferred embodiment of the custom accommodating artificial ocular lens (c-AAOL) device according to the present invention, a patient's vision may be corrected to 20:20, more preferably to 20:10, and even possibly to 20:7 and/or best correctable vision and the patient regains substantial to complete accommodation of the eye. In a most preferred embodiment, the custom accommodating artificial ocular lens (c-AAOL) device according to the present invention visually or optically corrects, protects, or otherwise overcomes any and all visual problems or defects.

The custom accommodating artificial ocular lens (c-AAOL) device is manufactured or designed after thoroughly examining, measuring and mapping the patient's eye or eye vision. This information is compiled and then processed to custom manufacture or make the custom accommodating artificial ocular lens (c-AAOL) device for the particular patient. For example, the patient's eye is evaluated for power correction, astigmatism correction, abnormal surface correction, abnormal refractive correction, abnormal tissue correction, and disease correction. For example, abnormal surface profiles or blemishes on the front and/or back surface and/or within the cornea and lens (e.g. natural lens or IOL) are analyzed by wavefront mapping and/or topography of the eye, measuring the internal dimensions of the eye, including cornea, anterior chamber, iris, pupil, posterior chamber, capsular bag, retina, to determine the condition of the eye.

The information from the eye examination, measurements and mapping are processed through a mathematical formula or algorithm embodied in a computer program to calculate the biological, chemical, and physical parameters or characteristics of the custom accommodating artificial ocular lens (c-AAOL) device to be manufactured or made. Specifically, the exact lens size, lens thickness, lens length, lens width, optic location, optic shape, material, material physical properties, material chemistry, material surface chemistry, material refractive index, material hardness, material resilience, material elasticity, material finish, front lens surface conformation, back lens surface conformation, lens curvature, and other processing factors or parameters are determined, and then transformed into machine language for controlling highly precise and accurate computer operated manufacturing equipment (e.g. digitally operated tools) such as lathes, mills, grinding machinery, laser, surface finishing machinery, or any other type of machinery or processes that can be computer operated and controlled for cutting the custom accommodating artificial ocular lens (c-AAOL) device or for cutting a mold for making the custom accommodating artificial ocular lens (c-AAOL) device

As another example, the custom accommodating artificial ocular lens (c-AAOL) device can be configured to adjust the overall or macro power of the eye and corrects the astigmatism of the eye. Specifically, the lens optic portion is provided with 1) a lens optic portion for changing the overall or macro power of the eye; and 2) a lens optic portion for correction astigmatism of the eye. For example, the power correction of the lens optic portion can be obtained by cutting or contouring the main overall or macro shape and thickness of the lens optic portion and/or the lens optic portion can be made multi-focal. The lens optic portion can be multi-focal by providing one or both surfaces of the lens optic portion with a multi-focal surface(s). The astigmatic correction of the lens optic portion can be obtained by providing a toric lens optic portion and/or by tilting (i.e. fixed or permanent tilt and/or varying tilting) of the lens optic portion. For example, one or both surfaces of the lens optic portion is provided with toric surfaces.

In a further example, the custom accommodating artificial ocular lens (c-AAOL) device adjusts the power of the eye, corrects the astigmatism of the eye, and corrects the fine or micro optics of eye based on wavefront analysis and mapping of the eye. For example, the power correction of the lens optic portion can be obtained by cutting or contouring the main overall or macro shape and thickness of the lens optic portion and/or the lens optic portion can be made multi-focal refractive and/or diffractive. The astigmatic correction of the lens optic portion can be obtained by providing a toric and/or diffractive lens optic portion. For example, one or both surfaces of the lens optic portion can be made with toric surfaces. Further; the lens optic portion can be made to provide point-to-point optical modification, adjustment, change or fine tuning of the structure and/or shape of the lens optic portion throughout the three dimensions (3-D) of the lens optic portion to micro fine tune or make micro modifications, micro adjustments or micro changes to the lens optic portion on a micro basis to eliminate any and all optical aberrations and provide for full wavefront optical corrections.

In a even further example, the custom accommodating artificial ocular lens (c-AAOL) device according to the present invention includes macro power adjustment, micro power adjustment, multi-focal, toric, and wavefront optics adjustment or correction on one or both sides of the accommodating (i.e. moving) lens optic, and/or within the interior of the accommodating (i.e. moving) lens optic portion.

The accommodating artificial ocular lens (AAOL) device can be custom made to correct any and all vision or optical problems or defects of the eye, including power correction, astigmatism correction, corneal surface and interior aberrations, lens surface and interior aberrations (natural or replacement lens, IOL), and other optical aberrations from other eye structure, eye aqueous and/or eye vitreous. In order to provided a custom accommodating artificial ocular lens (c-AAOL) device, it is required that the vision or optical defects of the eye are carefully measured, for example, by a visual field analyzer, slit lamp, biomicroscope and opthalmoscope. The goal is to provide an accurate and precise “eye assessment” to correct macro vision or optical defects or problems, and micro vision or optical defects or problems such as higher-order aberrations. The wavefront analysis based on adaptic measures of light deviations and aberrations can be measured to 0.01 microns (.mu.m) equivalent to approximately 0.001 diopter (D) adjustment by root mean square deviations (RMS units). Standard refraction methods are used to measure macro visual or optical defects or problems such as low-order aberrations (second-order sphere or defocus and cylinder in 0.25 diopter (D) steps. Up to twenty percent (20%) of the higher-order aberrations come from the corneal, aqueous, lens, and/or vitreous accounting for numerous changes in the indices of refraction of light rays moving through the eye.

The higher-order aberrations require measuring equipment exceeding standard or conventional refractive measuring instruments. The higher-order aberrations include coma (third-order), trefoil (third-order), spherical aberrations and quadra foil (fourth-order), and irregular astigmatism (fifth-order to eighth-order). These higher-order aberrations provide refractive abnormalities well below 0.25 diopter (D unit) translating to three microns (.mu.m) of tissue change within the eye. The wavefront analysis and mapping desired utilizes adaptive optics for measuring root mean square deviation (RMS) using measuring sensors such as a deformable “lenslent” systems to calculate RMS coefficients. The RMS coefficients are then converted into a polynomial pyramid (e.g. Zerneky Pyramid). The three dimensional (3-D) models or two dimensional (2-D) color maps indicate lower and higher order aberrations of the eye. The Zerneky polynomial measure aberrations up to the eleventh (11th) order, and can virtually analyze a hundred percent (100%) of the aberrations of the eye. Above the sixth (6th) order, only noise is created. Point spread functions (PSF) are used to measure and assess higher-orders aberrations in the human vision. These higher-order aberrations include distortions, haloes, tails, and/or double (overlapping) images.

The custom accommodating artificial ocular lens (c-AAOL) device can be made by selecting a material capable of being machined, and then cutting or contouring the front and back surface of the lens optic portion from a blank using a digital lathe, digital mill, laser, or by use of microlithography and/or etching to form or make lens structure or markings. For materials that can be molded, the lens optic portion can be made by machining and polishing a mold cavity, and then molding the lens from a desired material. In an example, the lens mold utilizes a replaceable insert, in particular a replaceable molding pin for molding the lens optic portion of the lens. In this manner, the molding pin can be replaced each time a lens is molded to make a one of a kind custom lens optic portion for a particular patient. The remaining portions of the mold (e.g. to mold plate haptic portion) can be of a standard size and shape, and otherwise not customized.

The molding pin for molding the lens optic portion of the custom accommodating artificial ocular lens (c-AAOL) device can be made by machining the molding pin surface thereof, and then highly polishing the molding pin surface. In a more preferred embodiment, the surface of the molding pin is machined, and then treated to provide a thin metal oxide layer thermally and/or electromagnetically deposited (e.g. vacuum deposited) to eliminate the need for the step of polishing the surface. Specifically, the molding pin is made of a copper/nickel alloy and the molding surface is diamond machined, and then a layer of corundum or aluminum oxide (e.g. sapphire, ruby, diamond (carboneaous)) is vacuum deposited on the molding surface to increase smoothness and durability thereof. The layer is preferably in the thickness range of fifty (50) to four-hundred (400) angstroms (.ANG.).

The custom accommodating artificial ocular lens (c-AAOL) device refractive correction lens can also be used to correct vision or optical defects or problems from prior surgical procedures and/or implants (e.g. after LASIK refractive correction of the cornea and/or after implantation of an IOL).

The subject matter of this application is also directed to an improved intraocular lens, for example, for replacement of the natural crystalline lens and/or an accommodating intraocular lens.

The intraocular lens comprises or consists of a lens optic or lens optic portion. The lens optic can exist by itself, or can be connected to a haptic portion, for example, one or more loop haptic portions or one or more plate haptics portions. The lens optic portion can be hard (e.g. made of hard material, hard plastic, polymethylmethacrylate (PMMA), acrylic, glass, or other biological compatible hard material), or can be deformable or resilient (e.g. made of soft polymer, hydrogel, silicon, collagen based polymer, or other suitable biological compatible materials of suitable refractive index.

The loop haptic, for example, is made of polyester, aramid fiber, or other suitable biocompatible material. The plate haptic portion is preferably made of a substantially flexible or resilient material and configured to allow the plate haptic to deform, flex, or bow when forces and/or pressures are applied by the eye onto the intraocular lens.

The intraocular lens or accommodating intraocular lens can be made as a single piece lens (e.g. by molding or machining), or can be made as a multiple-piece lens assembled together (e.g. hard or soft lens optic portion and resilient or deformable lens haptic portion).

The lens optic or lens optic portion of the intraocular lens or accommodating intraocular lens device can remain stable (e.g. substantially fixed in shape and size after implantation). Specifically, the lens optic or lens optic portion can remain in the same conformation, and is not deformed, bent, or bowed once implanted in the eye. Otherwise, the lens optic portion may not provide consistent light transmission and/or refraction during use or while the accommodating intraocular lens device is performing accommodation within the eye. However, it is to be noted that the lens optic or lens optic portion, in particular for a deformable type intraocular lens or accommodating intraocular lens, can be substantially deformed, rolled or folded during insertion, for example, through a small incision for implantation of the lens device into the eye. This type of lens then regains its operational shape and size, unrolls, or unfolds within the eye for placement in the appropriate position within the eye.

The intraocular lens or accommodating intraocular lens in one embodiment comprises or consists of a lens optic window, in particular a lens optic window configured to provide accommodation of vision of the eye. The lens optic window, for example, is located in the lens optic or lens optic portion of the intraocular lens. Once implanted, this type of intraocular lens provides for “static” accommodation of vision of the eye, since the intraocular lens itself, or parts or portions of the intraocular lens do not have to move relative to each other when implanted in the eye to still provide accommodation of vision of the eye.

The lens optic window (light window) is configured to allow for most light (i.e. light rays) to pass through (e.g. pass straight through) the lens optic window with a minimal to none light refraction or distortion.

It is understood that the intraocular lens can still move somewhat in the eye once implanted. For example, an aphakic intraocular lens may move when implanted into the capsular bag due to movement of the capsular bag, and a phakic intraocular lens may move with movement of the natural crystalline lens of the eye. Further, an anterior chamber lens may move very little or not at all. However, accommodation of vision of the eye is still provided based on optical principles even when the intraocular lens moves slightly or not at all when implanted in the eye.

The lens optic window can be provided in various arrangements or embodiments. For example, in one embodiment the lens optic window comprises a flat lens optic portion provided on one or both sides of the lens optic or lens optic portion. Preferably, a pair of overlapping flat lens optic portions (e.g. flat surfaces) are provided on each side of the lens optic or lens optic portion. The flat lens optic portions can, for example, be flat circular lens optic portions centered and overlapping and of the same size and shape provided on both sides of the lens optic or lens optic portion.

The flat lens optic portion can be provided on one or both sides of the lens optic portion, and can overlap, partially overlap, or not overlap. Further, the shape and size of the flat lens optic portion can vary on one or both sides of the lens optic or lens optic portion. For example, the flat lens optic portion is a flat shaped lens optic portion (e.g. circular-shaped or round, oval, triangle, square, pentagon, hexagon, octagon, star-shaped, gear-shaped).

The flat lens optic portion is configured to allow light to pass more directly through (e.g. straight through) the thickness of the lens optic or lens optic portion (e.g. pass through lens optic or lens optic portion perpendicular relative to a flat surface of the lens optic portion).

The flat lens optic portion(s), for example, can dimensionally be in the range of 0.5 mm to 4 mm, can be in the range of 0.5 mm to 3 mm, can be in the range of 0.5 mm to 2 mm, or can be approximately 1 mm. Further, the flat lens optic portion(s) can be circular and have a diameter(s) in the range of 0.1 mm to 4 mm, can be in the range of 0.5 mm to 3 mm, can be in the range of 0.5 mm to 2 mm, or can be approximately 1 mm.

As another example, the lens optic window comprises a lens optic tunnel (e.g. hole or holes, partial depth holes or recesses, tunnel, through hole, overlapping partial holes or recesses on both sides). Preferably, the lens optic tunnel can be circular-shaped or round, and centered in the lens optic or lens optic portion. The lens optic light tunnel can be provided on one or both sides of the lens optic or lens optic portion, and can overlap, partially overlap, or not overlap. Further, the shape and size of the lens optic light tunnel can vary on one or both sides of the lens optic or lens optic portion. For example, the lens optic light tunnel is specially shaped in two or three dimensions (e.g. circular-shaped or round, oval, triangle, square, pentagon, hexagon, octagon, star-shaped, gear-shaped, cylindrical-shaped, cone-shaped, tapering, funnel shaped, prism shaped).

The lens optic light tunnel is configured to allow light to pass more directly, or directly through the thickness of the lens optic or lens optic portion (i.e. pass through lens optic portion along focal axis or perpendicular to lens optic or lens optic portion surface and without passing through reduced thickness or no lens material).

For example, the lens optic light tunnel can have a width in the range of 0.5 mm to 4 mm, can be in the range of 0.5 mm to 3 mm, can be in the range of 0.5 mm to 2 mm, or can be approximately 1 mm. Further, the lens optic light tunnel can be circular and have a diameter in the range of 0.5 mm to 4 mm, can be in the range of 0.5 mm to 3 mm, can be in the range of 0.5 mm to 2 mm, or can be approximately 1 mm.

As a further example, the lens optic window comprises a flat lens optic portion and a lens optic light tunnel. Preferably, the flat lens optic portion and lens optic light tunnel are circular-shaped or round, and centered on the lens optic or lens optic portion. The flat lens optic portion and/or lens optic light tunnel can be provided on one or both sides of the lens portion, and can overlap, partially overlap, or not overlap, or configured as a through hole. Further, the shape and size of the flat lens optic portion and/or lens optic light tunnel can vary on one or both sides of the lens optic or lens optic portion.

For example, the flat lens optic portion and/or lens optic light tunnel are shaped (e.g. circular-shaped or round, oval, triangle, square, pentagon, hexagon, octagon, star-shaped, gear-shaped). The combination of the flat lens optic portion and lens optic light tunnel are configured to allow light to pass directly through the thickness of the lens optic or lens optic portion (i.e. pass through lens optic or lens optic portion perpendicular to lens optic or lens optic portion surface and travel the least distance through thickness of the lens optic or lens optic portion).

For example, the flat lens optic portion and/or lens optic light tunnel can dimensionally be in the range of 0.5 mm to 4 mm, can be in the range of 0.5 mm to 3 mm, can be in the range of 0.5 mm to 2 mm, or can be approximately 1 mm. Further, the flat lens optic portion and/or the lens optic light tunnel can be circular and have diameters in the range of 0.5 mm to 4 mm, can be in the range of 0.5 mm to 3 mm, can be in the range of 0.5 mm to 2 mm, or can be approximately 1 mm.

As a further example, the lens optic window comprises a lens optic insert. The lens optic insert, for example, can be provided in the lens optic or lens optic portion and configured to provide accommodation of vision of the eye.

For example, the lens optic insert can dimensionally be in the range of 0.5 mm to 4 mm, can be in the range of 0.5 mm to 3 mm, can be in the range of 0.5 mm to 2 mm, or can be approximately 1 mm. Further, the lens optic insert can be circular and have diameters in the range of 0.5 mm to 4 mm, can be in the range of 0.5 mm to 3 mm, can be in the range of 0.5 mm to 2 mm, or can be approximately 1 mm.

As an even further example, the lens optic window comprises a positive lens optic surface on one side of the lens optic and a negative lens optic surface on an opposite side of the lens optic. For example, the positive lens optic surface can cancel out the negative lens optic surface to zero out the lens power.

For example, the lens optic window, or lens optic surfaces, can dimensionally be in the range of 0.5 mm to 4 mm, can be in the range of 0.5 mm to 3 mm, can be in the range of 0.5 mm to 2 mm, or can be approximately 1 mm. Further, the lens optic insert can be circular and have diameters in the range of 0.5 mm to 4 mm, can be in the range of 0.5 mm to 3 mm, can be in the range of 0.5 mm to 2 mm, or can be approximately 1 mm.

As another example, the lens optic window comprises a diffractive lens optic portion.

For example, the lens optic window, or diffractive lens optic portion, can dimensionally be in the range of 0.5 mm to 4 mm, can be in the range of 0.5 mm to 3 mm, can be in the range of 0.5 mm to 2 mm, or can be approximately 1 mm. Further, the lens optic insert can be circular and have diameters in the range of 0.5 mm to 4 mm, can be in the range of 0.5 mm to 3 mm, can be in the range of 0.5 mm to 2 mm, or can be approximately 1 mm.

The intraocular lens or accommodating intraocular lens in an even further embodiment comprises or consists of a lens optic portion and a haptic portion. The lens optic portion can be connected to the lens haptic portion.

The intraocular lens or accommodating intraocular lens can comprise or consist of a movable lens optic portion and a fixed lens haptic portion, preferably a plate lens haptic portion, relative to the eye in particular the inner eye structure. The lens optic portion functions essentially as a separate component relative to the lens haptic portion, except for at least one flexible or resilient arm connecting the lens optic portion to the lens haptic portion. Preferably, at least one opening is provided between an outer edge of the lens optic portion and an inner edge of the plate lens haptic portion. More specifically, the lens optic portion is separated from most of the plate lens haptic portion by a space (e.g. fixed or varying distance). In this arrangement, the outer edge of the lens optic portion is able to move substantially freely and independently relative to the inner edge of the plate lens haptic portion, except at the point or points of connection with the flexible or resilient arm(s).

This embodiment provides for a type of accommodation with movement of the lens optic portion relative to the lens haptic portion. This embodiment can be combined with a flat lens optic portion and/or lens optic light tunnel to provide additional accommodation (i.e. accommodation provide by both static and dynamic arrangements to enhance accommodation effect).

In the accommodative movement embodiment, the intraocular lens or accommodating intraocular lens comprises or consists of at least one arm, preferably a flexible or resilient arm connecting the lens optic portion to the plate lens haptic portion. The flexible or resilient arm is configured to move the lens optic portion along the central focus axis of the eye when the plate lens haptic portion is deformed, flexed, and/or bowed, for example, when the eye exerts inwardly and/or outwardly radial forces at one or more positions around the outer edge of the plate lens haptic portion and/or on the front or back surfaces of the lens. More specifically, the lens optic portion is moved along the central focal axis of the eye for purposes of accommodation for focusing the eye when the plate lens haptic portion is bowed. At least one flexible arm allows the outer edge of the lens optic portion to move relative to the inner edge of the plate lens haptic portion, which becomes distorted as the plate lens haptic portion is bowed. In this manner, the at least one flexible or resilient arm accommodates tensile stress, shear stress and some torsional stress when the plate lens haptic portion is deformed, flexed, and/or bowed without breaking or permanently deforming. Specifically, the stresses are at a level within the at least one flexible or resilient arm when the plate lens haptic portion is deformed, flexed, and/or bowed so as to not cause plastic deformation of the at least one flexible or resilient arm. Thus, when the force on the lens is relieved, the stresses within the at least one arm are relieved and causes the lens optic portion to move back to a resting position relative to the eye.

The accommodative movement, for example, of the lens optic portion is initially located in the same plane as the plate lens haptic portion. When force is applied to the outer edge of the plate lens haptic portion, the plate lens haptic portion begins to bow and moves the lens optic portion out of the initial reference plane along the central focal axis of the eye. As the plate lens haptic portion bows, it changes shape from substantially from a two (2) dimensional configuration to a cupped or bowed three (3) dimensional configuration, and is substantially no longer planar.

The outer periphery or edge portion of the plate lens haptic portion can be configured and/or treated to facilitate or enhance anchoring thereof within the eye. Specifically, the plate lens haptic portion can be provided with one or more through holes to allow tissue on either side of the plate lens haptic portion to adhere together in the through hole. Alternatively, or in addition, the outer edge of the lens plate haptic portion can be provided with surface treatment (e.g. porous), scallops, serrations and/or notches to facilitate tissue adherence thereto.

In the accommodating intraocular lens, the lens optic portion can be circular shaped or oval shaped. Further, the lens optic portion can be centered relative to the shape of the outer periphery of the plate lens haptic portion.

As an alternative embodiment, the lens optic portion can be located off centered in one or both the length and width dimensions relative to the outer perimeter of the plate lens haptic portion. In this manner, the accommodating intraocular lens device can be customized to take into account the morphology of the interior structure of the eye of a particular patient in custom designing and prescribing the particular accommodating intraocular lens device for the particular patient.

The accommodating intraocular lens can have a pair of flexible or resilient arms connecting the lens optic portion to the plate lens haptic portion, the lengths of the arm portions can be the same or different. Further, the location of the pair of arm portions can be located along a center axis of the lens optic portion or can be located off axis.

As another example, the intraocular lens comprises or consists of a lens optic comprising or consisting of a ring-shaped lens optic portion. The ring-shaped lens optic portion can be configured to effect the optical properties or characteristic of the lens optic. For example, the ring-shaped lens optic portion is configured to block light transmitting through the ring-shaped portion, change the refractive properties of the lens optic, provide a diffractive lens portion(s), and/or provide a multi-focal lens portion(s).

The ring-shaped lens optic portion can be a ring-shaped mark(s) and/or a ring-shaped pattern provided on one or both surfaces of the lens optic.

As a further example, the intraocular lens comprises or consists of a lens optic window and a ring-shaped lens optic portion. The various examples of the lens optic window can be combined with the various examples of the ring-shaped lens optic portion to achieve a variety of optical properties and characteristics of the lens optic and intraocular lens.

For example, three (3) object distances, the type of structure (e.g. sine wave, trapezoid and/or rectangle), and the lens material can be specified for making the trifocal embodiment. In other embodiment, more than three (3) multi-focal surfaces or zone (e.g. concentric, symmetric, asymmetric, matrix arrangements of surfaces or zones) can be used for particular applications or custom made for a particular eye. Alternatively, lithography can be used to print marks or a pattern on one or both surfaces of the lens (e.g. grid, rings, matrix) to cause light diffraction to make a diffractive lens optic, or lithography combined with etching (e.g. lens mold surface) can be used to make nanometer to angstrom dimension profiles, protrusions, patterns, contours on lens surfaces to provide multi-focal and/or defractive lens surfaces.

A variety of embodiments of the accommodating artificial ocular lens (AAOL) device having different lens haptic shapes are shown in FIGS. 44-47.

In the embodiments shown in FIG. 44, the lens haptic portion 1714 is oval-shaped or spherical-shaped versus the circular-shaped configuration shown in the embodiment of FIG. 1.

In the embodiment shown in FIG. 45, the lens haptic portion 1814 is oblong-shaped. Specifically, the lens haptic portion 1814 has straight side portions 1814 a and circular-shaped end portions 1814 b.

In the embodiments shown in FIG. 46, the lens haptic portion 1914 has longer straight portions 1914 a (compared with the embodiment of FIG. 45) and circular-shaped end portions 1914 b.

In the embodiments shown in FIG. 47, the lens haptic portion 2014 has oval-shaped or elliptical-shaped side portion 2014 a and straight or square end portions 2014 b.

In the embodiment shown in FIGS. 48 and 49, the accommodating artificial ocular lens (AAOL) device 2110 includes a tapering lens haptic portion 2114. Specifically, the thickness of the center lens haptic portion 2114 a is substantially uniform and thin, and then begins to taper and thicken in an outwardly direction to define tapered lens haptic portions 2114 b. The tapering and thickening of the lens haptic end portions 2114 b strengthens the tapered lens haptic portions 2114 b towards the lens haptic portion ends 2114 a thereof to prevent bending along the length of the tapered lens haptic portions 2114 b. In this manner, as shown in FIG. 49, the tapered lens haptic portions 2114 b bend sharply at points 2115 (i.e. bending force is concentrated at positions 2114 b). This arrangement significantly increases the accommodating or throw distance D.sub.1 of the lens optic 2112 compared with an embodiment having a uniform thickness lens haptic portion.

To further illustrate this effect, a comparison embodiment of the accommodating artificial ocular lens (AAOL) device 2210 is shown in FIG. 50 having a uniform thickness lens haptic portion 2214. In this embodiment, the lens haptic portion 2214 bends uniformly from end-to-end (i.e. uniform curvature along length thereof) significantly reducing the accommodating or throw distance D.sub.2 compared with D.sub.1 of the accommodating artificial ocular lens (AAOL) device 2110. Thus, the tapering of the lens haptic portion provides for a greater accommodating or throw distance for the same amount of the force F.sub.1 being exerted inwardly on the ends of the lens haptic portion.

In the embodiment of the accommodating artificial ocular lens (AAOL) device 2310 shown in FIGS. 51 and 52, the lens optic portion 2312 is progressively tilted as the lens haptic portion 2314 is further bowed. The tilting of the lens optic portion 2312 increases to the optical power of the lens optic portion 2312. To provide tilting of the lens optic portion 2312, the circular-shaped lens openings 2318 a, 2318 b are made asymmetric in size and/or shape. Further, one side of the lens haptic portion 2314 can be made thicker and/or tapered verses the other side. Specifically, the left lens haptic portion 2314 a tapers in thickness outwardly from the lens optic portion 2312 while the right lens haptic portion 2314 b remains uniform and thin. In this manner when inwardly force is applied to the ends of the lens haptic portion 2314, the left lens haptic portion 2314 a does not bend while the right lens haptic portion 2314 b significantly bends causing the lens optic 2312 to progressively bow. The lens haptic portion 2314 can be designed to provide a linear progressive tilting of the lens optic portion 2312, or an exponential progressive tilting of the lens optic portion 2312 relative to the magnitude of the inwardly force applied to the ends of the lens haptic portion 2314 (or relative to the degree of bowing of the lens haptic portion 2314).

In the embodiment shown in FIGS. 53 and 54, the accommodating artificial ocular lens (AAOL) device 2410 is configured to laterally shift the center of the lens optic portion 2412 upon application of inwardly force applied to the ends of the lens haptic portion 2414. For example, the center of the lens optic 2412 is offset from the center of the lens haptic portion 2414, as shown in FIG. 53, when the accommodating artificial ocular lens (AAOL) device 2410 is in an unstressed condition. Further, the left lens haptic portion 2414 a is tapered in thickness to prevent bending while the right lens haptic portion 2414 b is uniform and thin in thickness. When inwardly force is applied to the ends of the lens haptic portion 2414, the center of the lens optic 2412 shifts to the left by a distance .DELTA.sub.C while the lens optic portion 2412 remains level or untilted. Alternatively, the cross-sectional size and/or shape of the connecting arms 2416 can be varied and/or the material varied to cause the same or similar effect.

An accommodating artificial ocular lens (AAOL) device can be configured to both tilt the lens optic portion and laterally shift the center of the lens optic portion in some applications by combining the features described above.

At the eye surgeon's office, the patient's eye is measured using visual field analyzers, eye charts and a topographer/abberometer. The abberometer measures the aberrations in the patient's eye and provides the eye surgeon with a topography map outlining all the aberrations. The eye surgeon uses the abberometer to check where the aberrations are coming from and analyze the data for different pathologies and make changes to the data where necessary. The abberometer is then used to generate a topography map and digital data that will be transferred to the manufacturer in the form of a customized lens order via satellite, internet, telephonic down load, CD ROM, DVD or mail or fax. Abberometer obtains the necessary information by using the Shack Hartman or means, which analyzes multiple beams of light transferred to the retina and then returned back through the eye. Variations of the light are measured against a light standard that would give perfect vision if all the parameters are met. The variation of the light is then compared against the Zerkeny polynomial to determine whether the variations are in the form of low order aberrations usually spherical and cylinder (toric) or high order aberrations such coma; trefoil (shapes showing in the optic system that look like a starburst usually around the periphery of the eye extending toward the center.

This information will then be received by the manufacturer, analyzed for completeness and any other kind of transmission errors. The data received is in the form of data points to be run through a program that to invert or reverse the information, since to correct an optic system requires making points or corrections that are opposite of the actual data received. This data will be run through the program to convert the data converted into machine language that will form a JFL file that will tell any equipment that can have varying cut (the Presitech Optiform with a variable forming tools or the DAC system with its toric generator) to cut a mold pin or optic in a form based on the information received from the eye surgeon's topography/abberometer, Zydekia Chart etc.

The order depending on the method of manufacturing can create a lens optic as part of the shop order or create a mold pin for the shop order in case of silicone manufacturing. The shop order would then go through the manufacturing process for developing lenses and a final lens optic would be made. During the process the lens would be marked in a manner so that the eye surgeon doing the surgery can tell where on the lens optic the changes are made. One side of the optic can contain all the changes needed for a multi-focal, toric and/or wavefront corrections, or some changes can be on the front side and some on the back side of the accommodating artificial ocular lens (AAOL) device depending on the patient and manufacturing constraints. In order to know that what was manufactured is what was ordered, similar equipment would be used to generate the data such as an abberometer using the same theoretical method to measure the reverse aberrations created in the lens and compare it with the original input information. The accommodating artificial ocular lens (AAOL) device is then sterilized and sent to the eye surgeon.

The manufactured lens data can be sent back with the lens to the eye surgeon, including data points and topography map with a manufacturing certificate for the eye surgeon and patient similar to a patient ID card, instead it would have a topography of the lens on the card.

The eye surgeon then inserts the lens haptic and lens optic into the patient's eye and places the accommodating artificial ocular lens (AAOL) device where needed based on what was ordered received. Minor adjustments in the lens optic and lens haptic can be made to obtain the appropriate axis of the optic. It is possible to make and optic off center in a mold pin combination if it were determined up front exactly where and if the optic needed to be changed from its center point. It is also possible to put adjustments items on the optic and haptic whereby the optic could be shifted up, down or side ways so that the multi-focal, toric, wave front can be lined up to give the patient better vision.

Lens Operation

The accommodating artificial ocular lens (AAOL) device according to the present invention is configured to bow or flex due to forces applied by the eye to the accommodating artificial ocular lens (AAOL) device, in particular to forces applied to the edge portions of the lens plate haptic portion.

The accommodating artificial ocular lens (AAOL) device according to the present invention can be located potentially in the anterior chamber and/or posterior chamber of the eye. Preferably the accommodating artificial ocular lens (AAOL) device according to the present invention in located in the posterior chamber of they eye, and more preferably is located in the capsular bag of the eye after cataract lens removal.

In operation, forces that are exerted on the capsular bag by the zonules of the eye are applied to the accommodating artificial ocular lens (AAOL) device according to the present invention, in particular to the peripheral edges thereof. As forces are applied to the outer edges of the accommodating artificial ocular lens (AAOL) device according to the present invention by the eye, the lens plate haptic portion begins to bow in an arch generally perpendicular to the flexible or resilient lens arm portions connecting the lens optic portion to the lens plate haptic portion so as to move the lens optic portion either forward or rearward from a resting position depending on the particular configuration and arrangement. In any event, the accommodating artificial ocular lens (AAOL) device according to the present invention is configured so that the lens plate haptic portion moves the lens optic portion during operation.

The operation or functioning of the accommodating artificial ocular lens (AAOL) device 10 according to the present invention is shown in FIGS. 23-26.

The accommodating artificial ocular lens (AAOL) device 10 is shown in an unstressed and unbowed condition, as shown in FIGS. 23 and 24. When inwardly directed forces F_(i) are applied around the perimeter of the plate haptic portion 14, the plate haptic portion 14 begins to bow relative to the X axis as illustrated in FIG. 25, and may furthermore be enhanced by varying hydraulic pressures in the eye. In this manner, the lens portion 12 is moved from a resting position plane P.sub.R to an accommodating plane P_(A) and traverses a distance .DELTA.sub.A. However, as illustrated in FIG. 26, the plate haptic portion 14 does not bow or substantially bow along the transverse axis Y, since the flexible or resilient lens arm portions 16, 16 reinforce and stiffen the lens plate haptic portion 14 from bowing along this transverse axis Y. Thus, the accommodating artificial ocular lens (AAOL) device 10 essentially bows in only a single dimension, and not in two (2) dimensions.

As illustrated in FIG. 25, the outer edges of the lens optic portion 12 become somewhat separated and exposed from the upper surface of the lens plate haptic portion 14 due to bowing of the lens plate haptic portion 14. In this manner, it is possible that the lens optic portion 12 could potentially extend into or through the pupil of the iris of the eye. However, as illustrated in FIG. 26, the lens arm portions 16, 16 do not allow the lens plate haptic portion 14 to bow in the transverse axis Y, and prevents the lens optic portion 12 from being exposed and separating from the upper surface of the plate haptic portion 14. Further, the arm portion 16 acts or functions like a pair of bumpers against the back of the iris at the opening of the pupil to prevent the lens optic portion 12 from entering into or passing through the pupil of the iris of the eye.

As illustrated in FIGS. 55 and 56, the lens optic portion 2512 remains flat in the X-Y plane even when the lens haptic portion 2514 is significantly bowed or bent due to the highly flexible nature of the connecting arms 2516. Further, the lens haptic portion 2514 can be provided with one or more marks 2515 (e.g. ink or indent) to facilitate placement and alignment when implant into the eye.

While this invention has been described with respect to various specific examples and embodiments, it is to be understood that the invention is not limited thereto and that it can be variously practiced within the scope of the following claims.
